Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.09159 | $0.09159 |
| Opus 5.5 | $0.03664 | $0.03664 |
| Sonnet 5.5 | $0.01832 | $0.01832 |
| Haiku 4.5 | $0.00916 | $0.00916 |
Grade B, and why
gridctl AGENTS.md scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.
~/.claude/settings.json. gridctl never executes a hook. Other clients are reported. How it starts
The opening of the file, as written. The whole thing — 358 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
Guidance for AI coding agents working in this repository. Follows the agents.md open specification: a single, predictable entry point for agent-relevant context. Human-facing onboarding lives in README.md and CONTRIBUTING.md; agent-specific tooling files (CLAUDE.md, etc.) re-export this file rather than duplicating it.
What gridctl is
Gridctl is an MCP (Model Context Protocol) gateway with a built-in skills and agents registry. A user declares a stack of MCP servers (containerized stdio, SSE/HTTP, OpenAPI-backed, local processes, SaaS proxies) in stack.yaml, runs gridctl apply, and gridctl orchestrates the containers, fans tool calls to the right server, aggregates downstream prompts and resources with registry skills, and surfaces every active SKILL.md to upstream clients as an MCP prompt. A projection engine (pkg/project, one lockfile at ~/.gridctl/project.lock.yaml) also places skills, agents, global-context rules, and gateway wiring onto disk for file-reading clients, and packs (gridctl-pack.yaml) import skills, agents, rules, and wiring from one git repo, may select skills and agents from declared external git sources pinned by commit (gridctl pack lock writes gridctl-pack.lock.yaml), can start an optional carried stack from a pinned checkout under ~/.gridctl/packs/, and can compose booster fragments onto that base daemon. The same process embeds a React web UI on :8180. Inspired by Containerlab.
Registry skills also expose io.modelcontextprotocol/skills through the existing MCP endpoints.
Handshake sessions opt in; stateless discovery declares it while the registry provider is available.
The global skill policy governs manifests and reads, including grouped endpoints. CLI skill lists
report local manifest summaries, including a per-row error when one skill cannot be hashed; status
reports declared extensions. The compatibility baseline is
tests/integration/skills-extension-baseline.md.
Build and run
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

gridctl AGENTS.md is an instructions file published in the GitHub repository gridctl/gridctl (46 stars, last pushed today), licensed Apache-2.0. It adds 9,159 tokens to every session, about $0.0366 per session on Opus 5.5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
